Shikonin Derivative DMAKO-05 Inhibits Akt Signal Activation and Melanoma Proliferation


, : Shikonin Derivative DMAKO-05 Inhibits Akt Signal Activation and Melanoma Proliferation. Chemical Biology & Drug Design 87(6): 895-904

DMAKO-05((S)-1-((5E,8E)-5,8-bis(hydroxyimino)-1,4-dimethoxy-5,8-dihydronaphthalen-2-yl)-4-methylpent-3-enyl 3-methylbutanoate) is a novel oxime derivative of shikonin, the major component extracted from Chinese herb Lithospermun erythrorhizon. Here, we report that DMAKO-05 had an antitumor activity against mouse melanoma cell line B16F0. Our studies indicated that DMAKO-05 not only inhibited B16F0 proliferation and migration but also led to cell cycle arrest at G1 phase and cell apoptosis, in which DMAKO-05 triggered mitochondrial-mediated apoptosis signal including caspase-9/3 and PARP. In response to DMAKO-05 treatment, the Akt-mediated survival signals were remarkably attenuated in B16F0 cells. Collectively, DMAKO-05 has a strong cytotoxicity in B16F0 cells via inhibiting Akt activation, inducing G1 arrest, and promoting B16F0 cell apoptosis. DMAKO-05 might serve as a potential candidate lead compound for melanoma.
